Disa the Restless + Mimic Vat + Phyrexian Altar

Disa the Restless

Mimic Vat

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing a nontoken Lhurgoyf, adding one mana of any color.
2. When the Lhurgoyf dies, Mimic Vat triggers, exiling the Lhurgoyf from your graveyard and returning the Lhurgoyf that was exiled to your graveyard.
3. Disa's first ability triggers, putting the Lhurgoyf from your graveyard onto the battlefield.
4. Repeat.
